AIM: The incidence of malrotation after femoral shaft fracture treated with close reduction and interlocking intramedullary nailing is high. To judge the degree of rotational deformity in fracture of shaft of femur by C-arm X-ray machine is necessary in the repair of tissue construction.

目的：采用闭合复位带锁髓内针置入固定治疗股骨干骨折，术中常出现远端旋转畸形，利用C形臂X射线机并以健侧NH角（股骨头－颈轴线与水平台面的夹角）作为参照物，判断骨折端旋转移位程度是组织构建修复过程中必须解决的应用技术。

Cupule subglobose, 3.5-4.5 cm in diam., completely enclosing nut, wall 4-6 mm thick and ± woody when dry; bracts subulate, 6-10 mm, woody and multiangular, base 4-8 mm in diam., apex shortly pointed.

壳斗近球形，直径3.5-4.5厘米，完全包裹坚果，壁4-6毫米厚，干时多少木质；苞片钻形，6-10毫米，木质多角，基部直径4-8毫米，先端短尖。

The results of research indicates: the shorter the radius is, the greater influence of the noncoincidence of the torsion center and gravity center for torsion angle will be.

研究结果表明，曲率半径越小，剪心和形心分离对扭转角的影响越大。

Inflorescence spikelike, cylindrical, composed of spiny or bristly deciduous burrs arranged along an angular, often sinuous rachis; burrs sessile or with an obconical basal stipe, each composed of 1 or more sessile spikelets surrounded by an involucre of spines and bristles; bristles flexuous or more often spinous,± flattened, grooved on the outer face, united below, the degree of union varying from a small basal disk to a deep cupule, inner spines or bristles often ciliate around spikelets. Spikelets lanceolate, acute; glumes unequal, shorter than spikelet, lower sometimes suppressed; lower floret membranous, staminate or neuter; upper floret firmer, protogynous.

花序穗状，圆筒状，由落叶的毛刺沿着一具角安排的具刺的或具刚毛，通常波状的轴组成；毛刺无梗或具基部的倒锥状柄，每一个由1无梗或更多组成以总苞的刺和刚毛包围；或更多的刚毛曲折通常spinous，多少扁平，在外面上具凹槽，下面的合生，协会的度从一小的基部的花盘变化到一深的壳斗，小穗披针形，锐尖；不等长的颖片，短于小穗，降低有时压抑；更低的小花膜质，雄蕊花的或中性；坚定的上面小花，雌蕊先熟。

Seeds many, oblong or oblanceolate, narrowly winged or angular.

种子多数，长圆形或倒披针形，狭翅或具角。
